PAPER-BEARING MACHINE.

Application filed June 9, 1917. Serial-No. 173,776. I

To all whom it may concern:

'Be it known that I, RICHARD F. MURRAY, a citizen of the United States, residing at Fort Edward, in the county of Washington and State of New York, have invented certain new and useful Improvements in'Paper- Making Machines, of which the following is a specification, reference being had to the. accompanying drawings.

This invention relates to paper making machines, and has for its primary object to provide certain improvements in the headbox mechanism from which'the paper pulp is fed, whereby the machine may be operated at very high speed to produce a high-grade product and with a minimum of wear upon the several mechanical parts.

It is one of the particular objects of the present invention to provide an improved adjustable apron board whereby wear upon the wire agitator which receives the pulp may be entirely obviated.

It is also another object of my invention to provide an improved sectional slice and means for relatively adjusting the sections thereof, and additional means for vertically adjusting the slice as a unit to regulate the thickness of the paper pulp which is delivered to the apron board and to render the same uniform.

It isalso one of the important objects of the invention to provide deckle angles at opposite ends of the apron board hingedly connected to the adjustable slice and adaptedto extend outwardly over the wire breast rollerand movable against one side of the slice so that the wire can be easily removed or placed upon the conveyer rollers.

And it is a further general object of the invention to generally improve and simplify the construction of machines of the above character, whereby a considerable saving intime and labor'is realized, as well as an appreciable economy in the use of the paper pulp, the several parts of my improved headbox mechanism being of relatively simple construction and capable of application to the ordinary paper making machine now in general use.

With the above and other objects in v ew, my invention consists in the novel features of construction, combination, and arrange.

ment of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which,

Specification of Letters Patent.

Patented Sept. 18, .1917;

Figure is a fragmentary sectional view contains the paper pulp, and within this boX a wire mesh roller 6 is arranged, the trunnions 7 of said roller being vertically. movable in the end walls of the box. This roller operates to continually agitate or stir up the paper pulp contained in thebox or vat and to cross the fibers of the pulp.- r 3 8 designates the breast "roll of an endlesswire screen 9, said roll being suitably mount-g ed at one side of the head box 5 and having one end of its axis operatively connected to one of the trunnions of the roller 6 by means of the endless belt indicated at 10. j

Upon the wall ofthe headbox next adj a l cent to the conveyor roller'8, an" angle bar 11 is arranged, the horizontal flangeofsaidj bar projecting over the upper edgeof the box wall while the vertical flange of the'bar extends downwardly upon the outer face'of the wall. The latter flange of the angle bar is provided adjacent to its lower edge and in spaced relation to the opposite iends of. said bar, with a threaded boss or lug 12. In; bearing brackets 13 secured to'the wall of: the headbox 5, the vertically disposed shafts 14 are rotatably mounted, said shafts being threaded and opcratively engaged in the 'respective lugs 12. The lower end of each shaft 1% has a bevel gear 15 fixed'thereto, said gears being. engaged by the similar gears 1'7 secured upon a shaft 16 which/issupported in the. arms or extensions 18 formed upon bearing brackets 13. This shaft is provided upon one end with a suit+ able hand wheel 19, whereby it may be con' venleiitly rotated. A disk 26' is also secured upon said shaft and disposed between the" arm 18 of one bracket and an angular lug 65 erally designates the headboX or vat which tends over the horizontal flange or the angle bar 11, said board being provided with an angular portion 24 extending downwardlyalong the inner face of the wall of the headbox 5. The other longitudinal edge of the flange of the angle bar 11, as shown at 26, to

support the laterally extending portion of the-apron board 23. As thus described, it

. be seen; that the apron board can be readily adjusted vertically by simply rotating the shaft 16, whereby the vertical shafts 14 are turned in the threaded lugs 12. The

i edge of the apron board may thus be properly spaced from the wire 9. As shown in v.Fig. 2, the upper surface of the apron board 23 may be provided with obliquely disposed, intersecting grooves. Either a plane or grooved apron board may be employed in accordance with the particular grade of Pap In conjunction with my improved apron board, I provide a sectional slice, whereby the thickness of the paper pulp fed over the board to the wire agitator 9 may be'reguseries of plates or sections 27, each of which lated as desired. This slice consists of a is provided on its upper edge with a laterally projecting, longitudinally extendingflange 28. A bar 29 is provided in its ends with angular arms 30 in which vertically disposed adjusting screws 31 have threaded engagement, the lower ends of said screws being rotatably mounted in the upper ends of standards 32 supported upon the walls of the headbox. nected at their lower ends by the bar 33 resting upon the hea'dbox wall. A pair of adjusting screws 34 is threaded in the flange" 28zon each section 27 of the slice, the lower ends of said screws being rotatably mounted in the bar 29. A lock nut 35 is threaded upon each screw 3a to engage the flange 28 and hold the slice section in its adjusted position. A similar lock nut 36 is also threaded upon each of the adjusting screws 3l for engagement with the lugs 30. By ad usting 1 the two screws 31 at opposite sides of the headbox, it will be understood that the several sections 2'? of the slice may be raised or lowered as a unit to space their lower edges from the bar 33. These several sections of the slice can also be individually adjusted by means of the screws 34:- 1'

The lower end of one of the standards 32 is provided ,with an outwardly projecting arm 36, in which one end of an adjusting screw 37 is swiveled for rotative movement. This screw has threadedengagement in an angular bracket 38 secured to one wall of the headbox. By the rotation of this screw,

These standards are con-' the sectional slice may be shifted longitudinally and disposed in the proper position.

Upon the standard at each end of the adjustable slice, a deckle angle 39 is hingedly mounted, as at 40, and is adapted to extend laterally from the slice in parallel relation to the line of movement of the pulp over the apron board. 23 adjacent to the opposite ends thereofas seen in Fig. 2, so as to prevent the lateral deflection of the pulp and consequent waste thereof. These declrle angles, by reason of their pivotal mounting, may be swung inwardly against the ad justable slice to a. position at right angles to the line of movement of the pulp. The wire screen 9 can then be easily and quickly removed from the roller 8 or placed thereon. Of course, the usual deckle strap, indicated at 41, operates above the wire screen 9 to carry the paper pulp from the apron board upon the agitator and retain the same on the latter. I

From the foregoing description, the construction, manner of operation, and several.

advantages of my invention will be readily understood. Heretofore, it has been usual to' arrange the slice on the opposite side of the breast roll-8 so that it held back a pond of water and the pulp stock. By mounting the fiber crossing roller 6 back of the adjustable slice, the strength and texture of the paper is greatly improved. The improved adjustable apron boa-rd prevents frictional wear upon the wire agitator which is caused by the canvas apron usually employed, dragging upon the wire. The use of such a canvas apron also makes it impossible to operate the machine at a high speed. WVith the improved apron, the machine can be operated at a maximum speed with entire safety. This apron board may be readily adjusted vertically to space the same from 'the conveyer as desired. The sectional slice and means for adjusting the several sections enables the operator to improve the product by preventing light and heavy streaks in the paper so that it will be of uniform consistency throughout. It will thus be appreciated that I have gi eatl y increased the efficiency of paper making. ma

ehinery by means of the present improvements and likewise reduced the manual labor incident to their proper operation; The several coiiperating parts of the mechanism above referred to are, of course, susceptible of some modification in their form, proportion and arrangement, and it is, therefore, to be understood that while I have herein disclosed the present preferred embodiment of the invention, I nevertheless reserve the privilege of resorting to all such alternative constructions as may be fairly considered within the spirit and scope of the ap ended claims.
